No …. not close.  You can talk to Rob about his tests, but that isn’t what he 
does.  And  any sensors between the signal generator and the radio (or your 
antenna and the radio) aren’t going to materially change anything about the 
radios performance.

How many tenths of a dB are you concerned about?  :-)
